We studied the role of nitric oxide synthase during tumor growth in oncovirus-induced tumor mutants of Drosophila melanogaster. The lines with different capacity for malignancy differed reliably in the level of enzymatic activity. It was shown using specific inhibitors of neuronal and inducible isoforms that the neuronal isoform was not involved in tumor formation, while the inducible one appears to play an important role in tumor growth inhibition. This isoform was identified with the help of immunoblotting and monoclonal antibodies against inducible nitric oxide synthase. 相似文献

Association between the polymorphism of DNA repair genes XRCC1 Arg399ln and XRCC3 Thr241Met and the frequency of chromosomal aberrations in the uranium workers was studied. The Gln/Gln genotype of gene XRCC1 was associated with a significant increase in the number of chromosomal aberrations as compared to the corresponding homozygous wild type Arg/Arg (p < 0.05). The frequency of chromosomal aberrations in heterozygous carriers of the XRCC3gene Thr/Met was lower than in the homozygous carriers of the wild type Thr/Thr (p < 0.001). 相似文献
